[quote=101300]I don’t know of any way to change those configs but you could try switching to lr-mame4all for the default emulator- that uses retroarch configs
The global retroarch input configs use select as coin insert on Final Burn Alpha, but not in advance mame or mame4all. Without coin insert, everything else is useless. I can’t even use the start + select hotkeys to exit the game. From what I understand, configs are in /opt/retropie/configs with /all being global. My retroarch.cfg inputs look like this and I am using RPi2 V3 beta4 image.
Edit: Ok so I figured out default settings on RPi2 V3 beta4 doesn’t use lib retro mame4all.
Change to default=”lr-imame4all”
